nearest tenth of a cubic meter?

Answers

Answer 1

Answer:

Step-by-step explanation:

Given

diameter of 41.6 m

So radius =41.6/2= 20.8

Solution

volume of a hemisphere=4/3πr^2

=4/3×3.14×20.8×20.8

=5433.9584/3

=1811.319

So the answer is 1811.319 =1811(nearest 10)

Find the midpoint of segment AB if A(3, 2) and B(-1,4) Select one: O b (2, 1) O b. (1,3) O c. (2,6) O d. (2,3)​

Answers

Answer:

B (1, 3)

Step-by-step explanation:

midpoint formula is m=(x1 + x2 / 2), (y1 + y2 / 2)

So the xs are 3 and -1 add them to get 2, divided by 2 is 1.

The ys are 2 and 4, which equal 6, divided by 2 is 3.

So (1, 3)

if a triangular sail has a vertical height of 83 ft and horizantal length of 40 ft, what is the area of the sail?

Answers

Answer:

A = 1660 [tex]ft^{2}[/tex]

Step-by-step explanation:

Area of the sail or a triangle is base times height

A = [tex]\frac{1}{2}[/tex](b x h)

Base is 40 ft (horizontal length)

Height is 83 ft (vertical height)

A = [tex]\frac{1}{2}[/tex](b x h)

A = [tex]\frac{1}{2}[/tex](40 x 83) =  [tex]\frac{1}{2}[/tex](3320) = 1660 [tex]ft^{2}[/tex]

Answer:

  P = 3x +32

Step-by-step explanation:

If we assume the short vertical edge at top center is 10 yards, as it was in two previous problems with this geometry, then we can find the area of the present parking lot as ...

  (x-2)(3x) + x(3x -10) +2x(40) = 6x^2 +64x

where the left vertical rectangle is 3x high and x-2 wide; the center area between vertical rectangles is (2x-2)-(x-2) = x wide and (3x-10) high; and the right vertical rectangle is (x-2 +3x)-(2x-2) = 2x wide and 40 high.

As we said, the right vertical rectangle is 2x wide, so the area that has P as one of its dimensions is ...

  A = LW = P(2x)

We want this to be the same as the existing area, so ...

  2Px = 6x^2 +64x

  P = 3x +32 . . . . . divide by 2x
